Application filed September 9, 1916. 8erlal No. 118,181.

To all whom it may concern:

Be it known that I, LAWRENCE Y nnenn, a citizen of the United States, reslding at Jackson, in the county of Hmds, State of Mississippi, have invented a new and useful Type-Wnter Cover; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to certain new and useful improvements in typewriter covers, and has for its object to provide a device of 'this character which embodies novel features, of construction whereby the typewriter is automatically moved into operative position when the cover is opened, and the cover automatically closed when the typewriter is released and moved into moperative position, thereby making 1t very easy to take proper care of a typewriter and keep it covered when not in use.

Further objects of the invention are to provide a typewriter cover or hood which 1s comparatively simple and inexpensive 1n its construction, which can be either built into a table or desk or constructed as a separate unit, which admits of the typewriter being quickly moved back and forth from operative to inoperative position, and vice versa,

and which can be adjusted to operate satisfactorily with any standard make of typewriter.

lVith these and other objects in view, the invention consists in certain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a longitudinal sectional view through a typewriter cabinet constructed in accordance with the invention, the doors being shown in a closed position with the typewriter carrying slide drawn rearwardly and housed within the hood.

Fig. 2 is a horizontal sectional view on the line 2-2 of Fig. 1, showing the doors as swung outwardly and rearwardly into an open position and the typewriter carrying slide as moved forwardly into operative position.

Corresponding and like parts are referred to in the following description and indicated 1n all the views of the drawings by the same reference characters.

Referrmg .to the drawings, which illustrate one embodiment of the invention, the numeral 1 designates a base board which has a length or depth somewhat greater than that of a standard typewriter, the rear end of the base board being provided with a hood 2 which is open at the front, and which s of a sufiicient height to receive a typewr1ter.- In the present instance this hood 2 extends over substantially the rear half of the base board 1. A slide 3 upon which the typewriter is designed to be mounted is superposed upon the base board 1. The rear end of the slide is provided with the laterally projecting wings 3 which may engage the side walls of the hood 2 to assist in directing the slide in its back and forth movements, while the forward end of the slide is provided at substantially the middle portion thereof with a downwardly projecting ear 4 which is received within a longitudinal slot 5 formed in the top of the base board 1. The bottom. of the slide 3 is also provided with rollers 6 which reduce the friction and enable the slide to move freely backand forth upon the base board as the device is operated.

A tension sprlng 7 is arranged within the groove 5 of the base board, the forward end of the said spring being connected to the ear 4 of the slide, while the rear end thereof is connected to a threaded stem 8 be increased or decreased, depending upon the weight of the typewriter which is mounted upon the slide. This spring normally tends to draw the slide back into inoperative position at the rear end of the base board 1, and when the slide is pulled forwardly into operative position, an opening in a latch plate 10 at the forward end of the slide engages the nose of a spring latch 11 upon the base board, thereby holding the slide against the action of the spring. However, as soon as the spring catch 11 is disengaged from the latch plate 10 the slide 3, together with the typewriter spring mounted thereon, is drawn rearwardly into inoperative position by the action of the 7. Suitable sockets 12 are provided upon the slide 3 for engaging the feet of the typewriter;

The open front of the hood 2 is arranged to be closed by means of a pair of doors 13 which are constructed to overhang the forward end or keyboard of the typewriter, and provide, in edect, a forward extension of the hood 2 when in a closed position. For this purpose the doorsare formed with downwardly and forwardly inclined tops l3 and fronts 13 which project laterally from sides 13, said sides being hingedly connected at 14 to the sides of the hood 2. Knobs or finger pieces 15 areprovided at the front of the doors l3'for manipulating the same, and the doors are adapted to be swung outwardly and rearwardly into inoperative position against the sides of the hood 2 when the slide 3'is drawn forward to bring the typewriter into operative position. The edges of the doors 13 and the forward edges of the hood 2 are correspondingly rabbeted or beveled. as indicated at 16, in order to provide tight joints and eliminate open crevices when the doors are closed.

Means are provided for automatically moving the slide forward to bring the typewriter into operative position when the doors 13 are opened. For this purpose the side 13 of each door is provided upon the interior thereof with a rearwardly extending arm 17 which is slightly odset inwardly therefrom so as to fit against the inner faces of the sidewalls of the hood 2 when the covers are closed. These arms 17 are provided at the forward ends with flanges 17 which are secured to the doors l3, and at the rear ends with wings 17* which are pivotally connected to link members 18, the rear ends of the said link members be ng pivotally connected at 19 to the respectlve laterally extending wings 3 at the rear end of the slide 3. With this construction, it will be obvious that when the doors 13 are opened the slide 3 will be drawn forward and the latch plate 10 at the forward end thereof brought into engagement with the spring catch 11, thereby locking the typewriter in operative osition. When the operator is through uslng' the typewriter, it is merely necessary for him to release the spring catch 11, whereupon the tension spring 7 will draw the slide 3 rearwardly into the hood 2, simultaneously closing the doors 13. The typewriter is then tightly housed so as to be protected from dust and dampness and there is little occasion for a careless operator to leave the machine-uncovered over night or when not in use.

The inner sides of the door 13 are provided toward the top thereof with trans verse straps 20, and toward the bottomtherepockets other opened up and the typewriter is in operative position. A pencil engaging clip 22 may also be applied to the inner faces of the sides 13 ofthe doors. if or the purpose of receivingletter heads or the like a shelf 23 may be provided immediately under the top of the hood 2, and the forward end of the top of the hood 2 may be formed with a transversely extending hinged strip 24 which can be swung upwardly to admit of the letter heads or paper upon the shelf 20 being easily grasped by the hand of the operator. Everything is thus within easy reach of the operator, so that much time will be saved in getting paper and envelops, and everything 1s arranged to be tightly housed when the typewriter is not in use.
